In tropical areas, parasitic diseases are very frequent during pregnancy. Malaria is the most frequent, with different complications in pregnant women (anaemia, cerebral malaria, abortion) and in the fetus (low birthweight, congenital malaria), mostly after first pregnancies. Diagnosis must be confirmed rapidly and the treatment is effective with most of antimalarial drugs. Prophylaxis is possible by intermittent sulfadoxine-pyrimethamine treatment. Hookworms infestation increases the anemia. Schistosomiasis can be liable to sterility or dystocia. Congenital transmission of visceral leishmaniasis is exceptional. Digestive parasitosis give few repercussion on pregnancy and their treatment is useful only if clinical troubles are important.
